TION OF MICHIGAN.

ToiaZvZ whom 'it may concern 'Be ity known that I, LYNN W. MAGOMBER) a Battle Creek, in the county of Calhoun and State -of Michigan,

new and useful Improvements in Baling- Presses; and I hereby declare that fthe f ollowing is a full, clear, and exact descrip,- tion thereof, reference being had to they accompanying drawings, which form part of this specification.

This linvention relates to balers, or machines for compressing light or lbulky material such. as waste papers, rags, etc., and its object is tov provide an efficient, easily operated, portable baler, which will be capa.- ble of withstanding rough usage, and in which all parts may be made of metal.

vparte The invention resides in -the novell construction and arrangement of parts of the baler, as hereinafter ymore particularly described withV reference tothe accompanying drawings and set fo-rth in the claims, it being understood however that the invention is not restricted to the specific proportions and construction of parts illustrated in the drawings, which however illustrate a practical baler embodying the invention.

In said drawings z--Figure 1 is a perspective lview of a baler with the follower or presser head raised, and the upper door open. Fig. 2 is an enlarged verticalY section through the baler, showing the operative vpart of the baler body being` broken away. Fig. 3 is van enlarged top plan view of the baler. ,Fig. t is a vertical section on line 4'-4, Fig. 2. Figs. 5 and 6 are detail sectional views. A

The baler comprises a body or baling chamber-which is preferably arranged vertically andicomprises opposite side walls 1b. which are preferably` and rear wall 1a stamped out of a piece of sheet steel and are rigidly secured to the metallic base frame l. The sides and rear walls ofthe baler are preferably braced by angle bars 1f as shown, to stiifen them.

The base frame l preferably projects beyond lthe front wallv of the chamber as shown and may be provided with rollers 1T,

so that byv tilting the baler forwardly its weight can Vbe transferred to these rollers and it can then be easily movedv from one position to another.

YThe baling chamber is yopen at top and its f Speccation of Letters Patent.

have invented certain BALrNG-rrtnss.

front .wall is preferably formed by a small upper door .2, and a larger door 3. The door 2 maybe stiifened by a top piece 2a and bottom angle bar 2b; this plate and bar project beyond the ends of the door and are adapted to be hingedly connected to a vertical rod 2c which is fastened to the projecting ends of the adjacent angle braces 1f on the sides of the baling chamber. The angle bar .2b projects beyond the free end of the doorV and is adapted to engage a hook or catcli-Qfwhichmay be formed by upturning the end of.V the adjacent bar 1f on the side of the baler as shown.

The lower door 3 may be braced by transverse'pieces 3X and is preferably hinged at its lower end to the frame by means of straps 3 which engage a hinge rod 3d passed. through the side pieces -of the base frame as sho-wn. The vertical side edges of this door arepreferably reinforced by angle irons L and the side flanges of these angle irons lap the side walls l"l of the baling chamber when the door is closed and prevent spreading of the side walls when the material is compressed in the chamber. The door 3 may be locked in closed position by means of latch rods'Sf, 3g pivotally connected 1 tol a lever 3h, at opposite sides of its pivot,

said lever 3h being pivoted at 3J' on the outer side of the door 3.v T he ends of these latch rods are adapted, when the door is closed, to engage. perforations in keeper straps 3i attached to the sides of the baling chamber and which project through slots 3k in they angle `pieces 3a when the door is closed, as shown in Fig. 1.

Adapted to operate vwithin the baling chamber isa presser head, which preferably consists of a metal frame 4 to the underside of which is attached a'metal sheet ta. This presser head is suspended from an Y operating frame comprising a transverse bar sideA with parallel flanges extending rearwardly, and their front flanges extend transversely of the baler and are slidably engaged with guides 6, which may beformed of strap metal, rigidly attached to a supporting arch or bar 6a extending transversely of and above the baling chamber and supported upon metal plates 6b attached to the upper ends of they side walls 1b of the baling Chamber and projecting above the same as shown. Y

rlhe guides 6 may be stiffened and held rigidly in position by means of inclined braces 6e, 6? attached to the guides and to the plates 6P as indicated in the drawings.

The front flanges of the actuating bars 5L are perforated, as at 5, for the engagement of pawls 7 which are pivotally attached to an actuating lever 7b (at opposite sides of the pivot of said lever) which is pivoted on a bolt 7c attached to the arch bar 6a intermediate the bars 5a. Preferably an auxiliary arch bar 6 is arranged beside and in front ofthe bar 6 to support the pivot 7c and assist in guiding the lever 7b and the dogs 7 in their movements.

Each dog 7 can be tilted on its pivot so that its tooth 71 can engage the notches or perforations 5 in the presser actuating bars 5f* when the'dog descends. When the dog rises its tooth will ride out of the notch. The dogs are pressed inward by means of lsprings 7e so that eachV dog will engage its related presser-actuating bar 5,va when said dog descends. It will be seen that when the lever 7 is moved up or dow-n one of the dogs will be raised and the other' will be lowered, so that they will Vwork in alternation, and therefore by oscillating lever 7b the presser head can be rapidly lowered andthe ma* terial in the baling chamber can be compressed according to the amount of leverage or force appliedto the lever 7 b. The dogs 7 maybe guided in their. vertical movements by means of slotted plates 61l attached to the guides: or braces. above the dogs as shown I in'Fig-s. l and 2'.

VThe lever. 7b may be operated from the side ofthe press; or it may be connected by a rod 7m to a lever 7n pivoted at 7 on one side of the baling chamber, which lever 7n can be readily operated by a person standing in front of the' baler; and it may be guided in its movements between a rod 7 D and strap 7 1. on the side of the baling chamber, as shown in Fig. l.

When it is desired to raise the baler head the dogs 7 must be disengaged from bars 5a; and for this purpose'I have sho-wn them as loosely connected by a chain 7 f; and by pullingon such chain both dogs can be disengaged from the bars 5a and the presser head raised. In order to raise-the presser head automatically I prefer to employ aspring 8, the lower end of which be fastened to a plate 5X secured between the platesj5?, and

the upper end ofthis spring is'attached to a bracket or plates 6h secured vto the upper ends of the guides 6 as shown. VThe spring is of such strength that it will Vnormally raise the presser actuating bars and the presser head suspended thereon to the highest position when thedogs are disengaged from the bars 5a; said Yspring being put under tension as the presser head is lowered. VVTo prevent the sudden lifting'of the presser head by contractionof the spring 8 a brake may be provided as shown inFigs. 5 and 6 comprising a shoe 6n adapted to engage the flange of one of the'bars 5*?, and adjustably pressed thereagainst bymeans of a screw 6 which may be provided with a lock nut 6P. This bolt can be adjusted so as tobind the flange of the presser bar 5a betweenv the shoe and thearch bar 6'l with sufficient frictional resistance to prevent too sudden or snap ac tion of the spring Elk in" raising the presser head. Y .Y v The presser head is preferably provided with three corrugations or grooves indicated at 4, and the front and rear bars of the frame 4 are notched as at/l1 adjacent'the ends of these corrugations, to enable the ties or wires WV (which are used to fasten a bale-when compressed) to be adjusted andk to have any slack taken up while the bale is undercompression. Y Y

I preferably provide at the top of the bal-- ing chamber and o n the rear wall thereof a Wire holdingy device comprising a metal vstrip V9v provided with notched flanges- 9,

with W-hich the ties vWare engaged. Adjacent each notch and attached tovthefplate 9 is a spring plate 9fwhich retains, the ties in engagement with the notches when inserted therein, the ties are slipped under' these springs and into the notches'in the flanges. A similar tie holder is secured inY retainers 9 at the top and bottom of theV chamber and the lowerV ends of the ties may be inserted through the 'openings 3 in the door 3 and the latter closed. rThe u'pper end ofthe wires can ble caught over the front edge of the rpresser heafd which is then raised to its highest position `and can be pressed backward partiallyl out of the chamber as indicated in dottedlines in Fig.V

Vpresser-head therein,

3. The door 2 can remain open yuntil the baling chamber is completely filled; then it is closed and the presser head pulled forward to the position shown in full lines in Fig. Then by operating the lever 7b bars 5a are forced downward, and the presser head lowered, forcibly compressing the material inthe baling chamber. When the material is. sufficiently compressed-the doors'Qand 3 may be opened and the ties can be readily adjusted under the head through the grooves @le and all. slack taken up and the ties united Ythus securely tying the bale; vthen thel dogs 7 are released by pulling on the chain 7 i whereupon the spring 8 immediately lifts the presser-head and presser actuating bars to thel position shown in Fig. 1, and the bale can befremoved, the springs 8 yielding suiiiciently to permit the disengagement of the Vties from the notches when the bale is tilted out of the chamber.
